Being turn-based, extreme FPS is less critical here. The game features high-fidelity models and uses considerable storage for audio and cutscenes. 8GB of RAM is recommended for smooth operation.
This game has a built-in FPS cap of 60 FPS
Actual FPS may vary based on RAM speed, background processes, and other system factors
Performance Report
At 1080p, all quality settings exceed 63 FPS. At 1440p, frame rates range from 57 to 69 FPS. At 4K, frame rates range from 45 to 61 FPS.
The GeForce RTX 4090 is 279% above the recommended GPU (GeForce GTX 1060) for Honkai: Star Rail. The Core Ultra 5 245KF is 102% above the recommended CPU (Core i7).
Honkai: Star Rail supports: AFMF. This game does not have native DLSS 3 or FSR 3 Frame Generation support. AFMF is AMD-exclusive and not compatible with GeForce RTX 4090.
The Core Ultra 5 245KF sets the FPS ceiling at all 1080p settings, all 1440p settings, all 4k settings, while the GeForce RTX 4090 still has headroom.
Approximated average price on current market:
Combo price: $1838. At 1080p Ultra, this combo delivers 63 FPS, equivalent to 0.03 FPS per dollar.

This section is based on estimated CPU/GPU FPS ceilings, not utilization percentages.
At 4k medium, the Core Ultra 5 245KF sets the ceiling at about 55 FPS, while the GeForce RTX 4090 could reach 110 FPS. In this scenario, the CPU limits the GPU potential by 50% (FPS gap: 55 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Core Ultra 5 245KF is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 38% | CPU Limits GPU 42% | CPU Limits GPU 34% | CPU Limits GPU 38% |
| 1440p (2K QHD) | CPU Limits GPU 34% | CPU Limits GPU 40% | CPU Limits GPU 32% | CPU Limits GPU 35% |
| 4K (Ultra HD) | CPU Limits GPU 46% | CPU Limits GPU 50% | CPU Limits GPU 42% | CPU Limits GPU 41% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
A component can still be the FPS limiter without reaching 100% utilization. The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

Yes, the Core Ultra 5 245KF paired with the GeForce RTX 4090 can run Honkai: Star Rail smoothly up to 1080p achieving around 63 FPS at Ultra quality. Your GPU is 279% above the recommended specs, and your CPU is 102% above the recommended requirements.
This CPU + GPU combo costs approximately $1838 ($189 CPU (Rank #10 Value) + $1649 GPU (Rank #77 Value)). Your Core Ultra 5 245KF provides phenomenal top-tier performance but at a premium enthusiast price. Since you are essentially at the ceiling of current hardware capabilities, there are no meaningful performance upgrades available. However, if you wanted a more cost-effective build that still delivers a great experience, you could theoretically step down to a high-end processor with a significantly better value rating. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
Your Core Ultra 5 245KF is already an incredibly powerful processor. While it's technically the first component to hit its limit (which is completely normal in state-of-the-art builds), there is no meaningful upgrade path that would drastically improve your Honkai: Star Rail performance right now. CPU fully utilized at: 1080p high, 1080p low, 1080p medium, 1080p ultra, 1440p high, 1440p low, 1440p medium, 1440p ultra, 4k high, 4k low, 4k medium, 4k ultra.
Honkai: Star Rail currently only supports AFMF (AMD Fluid Motion Frames) for frame generation, which is an AMD-exclusive technology. Because you are using an NVIDIA GPU, you cannot use Frame Generation for this specific game. However, the game does support DLSS Upscaling, which you should enable to render at a lower resolution and use AI to significantly boost your FPS without losing visual quality.
Honkai: Star Rail requires at minimum a Core i3 (CPU) and GeForce GTX 650 (GPU) with 6 GB RAM and 20 GB storage. For the recommended experience, you need a Core i7 and GeForce GTX 1060 with 8 GB RAM. Your Core Ultra 5 245KF and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These Honkai: Star Rail FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
